Did this as part of a larger circuit starting at Rhyd Ddu, climbing to Snowdon summit via the Rhyd Ddu path, to Y Llywedd, down to Pen-y-Pass, back up to the summit via Crib Goch and back to Rhyd Ddu via Bwich Cwmillan (near Quarry Upper Reservoir). Great hike and great views on the east side of Snowdon.

I climbed Crib Goch on the way to Snowdon from Pen-Y-Pass. A very interesting route...and apparently pretty underestimated, at least by quite a few of the people I saw there on that day with pretty inadequate shoes. It's definitely a "I+" route, and, contrary to so many routes of this kind in the Austrian Alps for instance, there isn't the slightest assistance such as metal ropes or ladders or anything of the kind, probably out of principle, which I would fully understand.
I loved Snowdonia when I was there, and I hope to go back someday!

Did the arete as part of the way up Snowden. Visibility wasn't great, but I remember being struck by the fact that I could see a crow soaring almost directly below me, when I looked over the edge at one point.

Descending the sharp part of the ridge, my boot twisted over and the weight of my 35 lb pack increased the forces causing a severe strain and stopped me doing the 3000s.
It will not deter me from going back though.
